Is there any function to automatically make a string uppercase or lowercase or to capitalize the first letter?I'm also looking to take a string and 'inspect' the first character so with : "example" i would want to get e as a variable.

Thanks guys. Both really helpful. One last question. What is the easiest way to check if the letter i extracted is a vowel. instead of writing a lot of if statements is there a way to check all vowels at one?Thanks
